Macduff's Opportunity?

        Macduff: The Apparitions themselves were even worried about him. Macbeth ignored that and decided to just confront him anyway. How did Macduff seriously become the right man in the right place at the end of the story? The story honestly could have been the same case scenario if the Apparition didn't warn Macbeth about Macduff, cause he thought just because he couldn't have been killed by anyone (born of a women) that mean't that he was unstoppable. It's pretty intense to think about how Macduff himself affect the entire story by mere coincidence and how much he went through to end up in the right place and to get the best outcome for his army. It is intense to think just imagine how unlucky Macbeth is as a main character to be tricked into thinking he was going to live a life full of power, just for it to be a set up for Macduff to finally put that sword up against his head...
